Iron(2+) and phosphate interactions in bacterial ferritin from Azotobacter vinelandii

Autor: Richard B. Frankel, Georgia C. Papaefthymiou, Heqing Huang, Deloria B. Jacobs, Gerald D. Watt

Publikováno v: Biochemistry. 31:5672-5679

Fe2+ binding to both apo- and holo- bacterial ferritin from Azotobacter vinelandii (AVBF) was measured as a function of pH under carefully controlled anaerobic conditions. Fe2+ binding to apo-AVBF is strongly pH dependent with 25 Fe2+ ions/apo-AVBF b

A facile method of isolation for the iron molybdenum cofactor of nitrogenase and bacterial ferritin from extracts of azotobacter vinelandii

Publikováno v: Inorganica Chimica Acta. 151:227-232

An alternative method has been developed for the isolation of both the iron molybdenum cofactor of nitrogenase (FeMoco), a small molecular weight FeMoS cluster which is the putative nitrogen- reducing site of the enzyme, and bacterioferritin, a

Publikováno v: Biochemical and Biophysical Research Communications. 121:1042-1047

Formate dehydrogenase ( FDH ) from Clostridium thermoaceticum is a known tungsten enzyme. FDH was tested for the presence of nitrogenase-type cofactor and nitrate reductase-type cofactor by the Azotobacter vinelandii UW-45 and Neurospora crassa nit-1

Redox reactivity of bacterial and mammalian ferritin: is reductant entry into the ferritin interior a necessary step for iron release?

Autor: G. D. Watt, Deloria B. Jacobs, Richard B. Frankel

Publikováno v: Proceedings of the National Academy of Sciences. 85:7457-7461

Both mammalian and bacterial ferritin undergo rapid reaction with small-molecule reductants, in the absence of Fe2+ chelators, to form ferritins with reduced (Fe2+) mineral cores. Large, low-potential reductants (flavoproteins and ferredoxins) simila
